Be 1t known that I, RICHARD E. F LYBERG,

a -citizenof the UnitedStates, residing at' more particularly to-thatclass in which therecoil resulting from the ring of one cartridge is utilized to bring another cart-ridge in position'ior iring'and to eject the iired shell.

The objects of my invention are to provide a firearm in which a number oi cartridges may be carried and to provide means for preventing pulling of the trigger until it desired to iire the arm.

The invention further includes means for preventing operation of the parts of the arm after the last cartridge in the magazine has been fired.

In the accompanying drawings, Figure lis a side elevation of a pistol embodying my in- Fig. 2 is a similar view of one side of the same, the casing being broken away.

Fig. 3 is a similar view of the other side of the same.' Fig. 4 is a side elevation with the casing removed, showing the' parts in the position they assume 'after iiring. Fig. 5 is a rear. elevation. `Fig. 6 is a detail sectional View through the hrccclrblock. Fig. 7 is a Fig. S isa detail side elevation ofthe ockjngvbolt for the breech-block. Fig. 9 is a detail side elevation of the trigger' and its associated parts Fig. 10 is a detail vertical sectional View through tlv-.magazine Fig. 11 is adetail sectional view through a modii'ied form of breech-block.

Referring 1.o the drawings, 1 denotes the stock of my pistol, and Z the barrel of the The stock is provided at its upper' same. end with spaced walls 3, between which is seated the breech. of the barrel 2, the breechbloek 4, and a guide-block 5', the latter being held in position hy means of ribs (i on the walls 3 of the stock, the said ribs being engagcd in grooves 7 1n the saidguide-block 5.

The breeclnblock' Ltis slid ably mounted in' the recess formed by the walls 3 of the stock Vand is provided. with a longitudinal bore 8,

which` terminates slightly short of the front end of the same. The guide-block 5 is arranged to receive the breech-block 4, and be tween the walls 3 in rear of the guide-block is a spring-guide 9, including a head 1U, having a transverse aperture 11 and a guide-pin' .12, over which is engaged a helical spring 13, which is also engaged in the bore 8 oi the breech-block. Through the aperture 11 'in the head 10 and the walls 3 lis engaged a screw 14.

vOn each side of the y breech-block 4 is formed'a rib 15, which is slidably engaged in grooves 16, formed in the guide-block 5, and in the forward end of' the block below the bore 8 is formed a slot-17, in which is slidably mounted a firing-pin 18, provided on vits outer'e'dge with a lug 19 for engagementby the hammer of the pistol. Engaged hori- 'Zontally tl'irougha slot 2() in the pin 18 isa screw 21, which has its otherend engaged in the. end of a screw 22, which is in turlf Inthe forscrewed into the breech-block 4. ward end of the breech-block is formed a recess 23, in'which is received the head of a cartridge, and directl)r above said recess in the breech-block is pivotcd an extractor latch 24, which is held in engagement with the head of a cartridge in said recess hy means of a helical' spring 25, seated in a bore 26 and held therein by means of a screw-plug' 27. On the'under side of the breech-block. 4 and to one side of the center of the samois formed alug '28, which is adapted ,to engage a hammer 29 to cock the saine. A groeve 3l) extendscentrally and longitudinally oi' thc under side of the breech-block for a purpose presently to be explained.

' The hammer 29 is pivoted in tho stock -to one side of the center there-oi and is provided -with the usual link 31 andrspring 3;. A lug 33 is formed on the hammer and is ln'ovidvd with an abrupt face for engagement with a lug 34 on a collar 35 to hold the .hammcnin cocked position, and a leaf-spring 35 has its end-in engagement with said lug 34' to hold ears forinedby the bifurcation of therod 41 ispivoted on the bolt 4() a trip 42, arran fed' to contact Wtha second lug 43 on the c'o lar I3-5 when'thetrigger 38 is pulled back to re- IOS .lease the lug'34 from the hammer 29, as will caved in rear of the lun 'end of the bore by -limit the movenu-mt of the latch.

the groove Sin the breech-block 4.

be readily understood. A spring 45 is provided to hold the trip 42 normallyin position to engage the lug 4l A bore 44 is provided in the rear end of the stock l, and in the. bore is slidably engaged a bolt 45, which is normally held in the Lipper means ot' a helical sprmg 46, which is held in the bore by means of a screw-plug 47, A lever 48 is pivoted in the stock above the bore 44 and is provided at its lower end with a lug 49, the under edge ofy which is inclined forwardly and engages a shoulder 50, formed by a recess in the side of the bolt 45. The end'ot the rod 41 in engagement with the upper end oiE the bolt 45, and a spring 51l is secured to the lever 48 and engages the rear end oi" the. stock l.

It will be readily understood that the rod 41 may be released, thereby releasing the trig rer, by pressing the lever 48 in toward the stocr, causing the lug 49 to engage the shoulder and lower the bolt '45.

It will be seen that by simply grasping the stock the lever 48 will be operated to release the trigger-locking mecluinism.v To hold the.

lever 48 in position to lock the trigger, a bolt 52 is provided. One side of the bolt is concavel to allow for the passage of a lug 53 when it is not desired to hold the bolt in the path of the rod 41. The lever 48 is con- 53, and in order to lock the lever 48 the bolt ,52 is turned by means of the linger-piece 5 4 untit the convex [side of the bolt Y is seated in the concave portion of the lever 48.

'Pivoted'in the v bolt 55 for. the breech-block 4. A-link 57 is pivoted to the. locking-bolt 55 by means of a pin 59 and to the stock by means of a screw 60, and secured to the stock and in engagement with the under side of' the lockingbolt is aspring 60.

vDisposed below the breech-block and in the stock -1 is a magazine. 61,-whieh is held therein by means of a spring-latch 62, which engages a notch 63 in the magazine 61. rThe spring-latch 62 is held in the stock by means ot a screw G4, anda stop-pinis provided to zine. `61 is close-d at the bottom and open at the. top and is provided atvits rear upper'edge with an ejector-lug 66, which is engaged in Slidably mounted in the magazine 61 is atolloWer67, and secured to the rear end of the same is a stop 68, which when the last shell has been ircdprojects in the. path ol the breech-lock and pri-vents operation ol" the arm, until it is depressed.

ln Fig. latch. shown. .ln this case theiati-.h comprises a leaf-spring (it), secured to the breechguide-block 5 is a locking- 11 a modified form ol' 4e.\'tractor block by means of a screw 70 andprovided upon its free end with an ejector-lug 71.

The recoil from the first cartridge iired moves the breech-block 4 rearwardly into the guide-block 5 against the tension of the spring, the loeking-bolt 55 being disengaged from the breech-b1ock by the link 57, it being understood that the barrel, the breech-block, and the guide-block have an initial bael ward movement which is sufficient to diseni said means vbeing arrangedfiim' actuation when the stock is grasped.
